Version: (using KDE KDE 3.5.5) Installed from: Debian testing/unstable Packages As many, many people will be able to confirm, you click 'Search' instead of 'Continue'. Putting a Continue button below the application selection box would nicely solve this within secods. Filed as bug because is severely impairs usability of bugs.kde.org
In light of the impeding KDE4 release, I am going through all bug reports I am involved in. To the best of my knowledge, this issue is still open.
